VALVE.

Specification of Letters Patent. e Pat-gnigd Blah 28 1g2.2

Application filed June 19, 1920. Serial No.` 390,239.

To f/,ZZ 'zu/71,0712.y t may concern lBe it known that I, BERTHOM) P.BLAUERT, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Valves, of which the following is aspecification.

\ This invention relates to valves which may be utilized for variouspurposes, but which are particularly adapted for use in connection withsupplying water to concrete miX- ers. In supplying water to thesemachines, a measuring tank is ordinarily used which is lled from anysuitable source of supply, and the water is then discharged from thetank into the mixer. This operation must be repeated very frequently,insome instances, about once a minute, so that quick operating valvemechanisnr is necessary. Furthermore, hot or'cold water may be used, andthe valve must be'adapted to operate with either kind. yMany of theordinary valves which are now in common use, may

yoperate successfully for cold water, but will not operate withoutconsiderable adjustment with hotwater.

The objects of the present invention are to 'provide a quick operatingmulti-way valve which is `adapted to be used with liquids or fluidsunder various temperatures; to provide a simple and eicient valve whichwill close one port and open another; to provide avalve for concretemixers which will operate with either hot or cold water, and in'general, to provide such an improved valve construction as will bedescribed more fully hereinafter.

In the accompanying drawings illustrating this invention:

Figure 1 is a side View;

Figure 2 is a sectional plan view taken on the line 2 2 of Figure 1;

Figure 3 is a sectional view taken on the line 3-3 of Figure 2,

Figure 4 is a cross-section taken on the line 4 4 of Figure 3; and,

Figure 5 is a cross-section taken on the line 5-5 of Figure 3.

In accordance with my invention, I provide a valve body 6 which ispreferably made of a single casting, and provided with the necessarypassageways. The body has a chamber 7 at one end having an intakeoriflee 8, and an outlet orifice 9. The intake is threaded or otherwiseconstructed to receive an intake pipe 10 from any suitable source ofsupply. The outlet orifice is also threaded to receive a pipe 11 whichmay lead to the measuring tank (not shown). The orifices 8 and 9,substantially constitute a through passageway which may be'opened andclosed by av suitable valve member, such as theslide valve 12, which isadapted to engage with seats13. The valve slide 12 is preferablyprovided with guideways 14, to engage with guides 15 in the sides ofthechamber 7. The valve slide 12 is connected to a valve rod 16 in anysuitable manner, but preferably so as to allow sufficient play for thevalve to seat properly. This is accomplished by having the rod 16provided with a head 17 which engages with a recess 18 in the valveslide, shown in Figures 3 and 5. The chamber 7 is closed at its outerend by a cap or bonnet 19, which has a suitable packing y20 for thevalverod 16.

. The body6 has a' chamber` 21 at the end opposite the chamber 7. Thechamber 21 has an inlet port`22 which is connected by a passageway 23with the port 9.* It has an outlet port 241 which is arranged to receivean outlet pipe 25. bythe ports 22 and 24 is opened and closed by a valvevslide 26 which is a vduplicate of the slide `12 rand which is actuatedby a rod 27. The `chamber'21 is closedby a cap or bonnet 28 having apacking 29 for the rod 27 Any suitable means may be provided foractuating the valves 12 and 26 simultaneously. In the arrangement shown,the rod 16 is connected to a cross-rod or arm 30. The ends of this armare secured to rods 31, which extend longitudinally of the body, and areguided by vbearings 32 on the sides The' passageway provided Y of thebody. The opposite ends of the rods 31 are connected by a pin 33, whichpasses through the rod 27. The body 6 has an arm or projection 34 towhich is pivotally connected, an operating lever 35 having a slot 36 forreceiving the pin 33. It will `be seen that when the lever 35 is movedback and pipe to the mixer. It will be seen that these valves may beoperated very rapidly andon account of the valves being tapered toengage with tapered seats, theywill tend to maintain tight closures, andwill also operate successfully with either hot or cold wa- Vter withoutany adjustment. Y

My improved valve may be made in various sizes, and different forms inorder that it may be utilized for different sized machines and indifferent positions. Therefore, l do not wish to be limited to the exactconstruction herein shown and described, eX- cept as specified in thefollowing claims, in which I claim:

1. In a valve construction, the combination of a body having avpassageway through one `portion thereof, a slide valve for controllingsaid passageway, a second passageway through another portion thereof, aslide valve for controlling said second passage# way, valve stemsconnected by loose joints to said slide valves and extending out throughthe body-, means connecting said stems for operating themsimultaneously, pipe connections leading from said passage* 'ways at oneside of the body, a'passageway connectingk said rst named passagewaysatk the other side of the body, and a pipe connection from said lastnamed passageway.

2. A valve construction comprising a body portion, having a chamber atone end thereof, an inletorice to and an outlet oriicej from, suchchamber, a tapered slide valve for controlling said inlet and outletorifices, a valve rod connected with said valve and extending out fromsaid chamber, said body having a second chamber with an 1nlet and anoutlet orifice, a tapered slide valve nection from'said passageway, across arm connected to the first-named valve rod, a pin through thesecond rod, longitudinal rods connecting said arm and pin and anoperating lever connected to the pin forreciprocating said rods andvalves.

`3. The combination of a valve body having a chamber at one end thereof,an inlet oriiice and an Outlet orifice for said chamber, a tapered slidevalve for opening and closing said orifices, a rod connected with saidvalve and extending out through the end of the chamber, said bodyhavingva second chamber in the opposite end thereof, an inlet orificeand an outlet orifice for said second chamber,l the inlet orilice'of thesecond chamber being connected with the out let orifice Vof the firstchamber, a tapered slide valve for opening and closing the orifices ofthe second chamber, a rod connected to said valve `and extending outthrough the end of the chamber, a cross-piece connected to thefrst'n'amed valve rod, two rods connected to said cross-piece andextending longitudinally of the body, apin connected with said lastnamed rods and passing through the second valve rod, an arm projectingfrom said body anda lever pivoted to said armV and engaging with saidpin for actuating the valves.
